I owned an American L-1505 and never got the hype. I already had my first StingRay5 at the time so had the oportunity to extensively A/B them. As much as I've always read people saying the 1505 is the logical evolution to a SR5 I strongly disagree. First of all the electronics hum annoyingly (didn't come shielded from factory -back then, I insist, maybe now they do-, had to shield it myself and even then you could still hear the hum). Then the onboard EQ is goofy (and I'm being generous) as in real life it provides for just a treble boost. Tone isn't too bad, still I prefer the SR5's (WAY more authority), which also offers more pickup options, that do produce in fact different sounds, much unlike the 1505's switch which I strongly suspected wasn't even wired before opening the control cavity (it was, and still it did wack for me tonewise). Last, but not least, playability was light years away, in comparison the neck on that thing was terribly thick (and probably Fender like, which I don't like much apart from Geddy Jazzes), which made thru-body stringing a no-no from the beginning for me. Still, I put effort in using it as my main bass for more than a year, then gave up and sold it in deep frustration. Checked a friend's late 2000's american L-2500 not long ago and it still had ridiculous electronics and playability still sucked, didn't hum as much as I recall mine humming. Liked the tone more with the 2 pickups 'tho. But no, I never got the hype, yet hear many praise them so I simply think they're not for me. Happened the same to me with Ashdown amps and cabs, some people hear heaven out of them, I just keep hearing dead sounding fart.
